Flowfit CYA27 Basic safety instructions

Endress+Hauser 5

2 Basic safety instructions

2.1 Requirements for the personnel

• Installation, commissioning, operation and maintenance of the measuring system may

be carried out only by specially trained technical personnel.

• The technical personnel must be authorized by the plant operator to carry out the

specified activities.

• The electrical connection may be performed only by an electrical technician.

• The technical personnel must have read and understood these Operating Instructions

and must follow the instructions contained therein.

• Faults at the measuring point may only be rectified by authorized and specially trained

personnel.

Repairs not described in the Operating Instructions provided must be carried out only

directly at the manufacturer's site or by the service organization.

2.2 Intended use

The assembly is specially designed to hold sensors. This includes in particular membrane-

covered disinfection sensors, e.g. Memosens CCS51D and 12 mm sensors with Pg 13.5

thread adapters and 120 mm (4.72 in) installation length, such as pH or ORP sensors,

oxygen sensors and conductivity sensors. Thanks to its design, it can be operated in

pressurized systems.

Use of the device for any purpose other than that described, poses a threat to the safety of

people and of the entire measuring system and is therefore not permitted.

The manufacturer is not liable for damage caused by improper or non-designated use.

2.3 Workplace safety

As the user, you are responsible for complying with the following safety conditions:

• Installation guidelines

• Local standards and regulations

2.4 Operational safety

Before commissioning the entire measuring point:

1. Verify that all connections are correct.

2. Ensure that electrical cables and hose connections are undamaged.

3. Do not operate damaged products, and protect them against unintentional operation.

4. Label damaged products as defective.

During operation:

‣If faults cannot be rectified:

products must be taken out of service and protected against unintentional operation.

2.5 Product safety

2.5.1 State-of-the-art technology

The product is designed to meet state-of-the-art safety requirements, has been tested, and

left the factory in a condition in which it is safe to operate. The relevant regulations and

international standards have been observed.

3 Product description

3.1 Product design

The Flowfit CYA27 is a modular assembly designed for operating sensors for liquid

analysis with a continuous flow of medium. The sensors are placed in specially adapted

modules. Due to its modular design, the assembly is flexible in terms of the number, type

and position of sensor slots.

For additional functions, the assembly can be fitted with optional accessories, e.g.:

• Status lighting to indicate the operating status

• Flow switch for monitoring the flow

• Flowmeter for flow measurement

• Sampling valve for direct sampling at the assembly

• Particle filter for particle reduction
